"ABSOLUTE CODSWALLOP"

Do not use. I am still waiting for the results of my day 2 PCR test which Royal Mail tracking says the lab received 5 days ago.
The phone number has an automated message saying send an e mail. The e mail response I received says I have made an error and not activated the test. - CODSWALLOP - they are now trying to blame me for their incompetence.

"No contact no one answers phone"

No contact no one answers phone . No results from my fit to fly ever came .
Sent over 10 emails just an automated reply
DONT USE
Ps just Look at their terms and Conds

"I had 5 days in quarantine and am on my way back."

I arrived in UK at late Nov 30 so I had to have PCR test. I completed my test at Dec 1 morning and dispatched it. Today is my return day and I still didn't receive my result yet.
I think I could only receive my result after returning.

"Don't rely on them to get a test in time."

Ordered a day 2 lateral flow test. Did not receive lateral flow test before going on holiday. Govt changed their mind to require PCR test. Had still not received day 2 test when back from holiday. Emailed them to see where test was anyway. They decided to send me a pointless replacement day 2 lateral flow test anyway to be received on day 3 so that they fulfilled their 'obligation'. Would never use again.

"DO NOT USE"

DO NOT USE, buyer beware. Paid my fees sent back as instructed within the timeframe required and yet NOTHING no test result no response to my numerous emails and unable to contact by phone!

"I contacted them for an important…"

I contacted them for an important question during my holiday. Never received an answer and I had to rebook a different test from another company.

"AVOID, AVOID, AVOID!!"

Ordered the PCR testing kit whilst abroad expecting it to be there for our arrival home, nope, 24 hours late equating to one unnecessary day isolating! Posted and tracked back next day. 3 days later still no cigar! Hacked off with being forced into isolation by their complete incompetence. Annoyed by the inability to contact them. Can’t believe the government endorse these jokers. Should have just set fire to the money! Avoid or use at your peril!

"PCR results delay more than 24h"

Me and my fiancee had bought a PCR kit test and submit as required. The teste with should be delivered results was not delivered yet and has been more than 24 hours. We came from Brazil only to see HARRY POTTER studios, which in our currency is 8x expensive and we can not go because rainbow labs does not send us the pcr results. We have email them a lot of times, but no return was received.

"I used them previously for lateral flow…"

I used them previously for lateral flow tests (last month).. no problem at all. Now everything has changed and the day 2 PCR test is now needed .. and the wheels have fallen off the Rainbow machine .. all except their cash register that is !
No results 48 hours after they revived the sample and no email explaining anything, no number to call .. nothing !
This is greed at its worst . Taking the money when they know they do not have the capacity to deliver .

"DO NOT USE RAINBOW LABS"

DO NOT USE RAINBOW LABS.
I ordered and paid for two day-two LF tests. I received reference numbers but did not receive the test kits. I contacted them by email several times but only received an automatic response promising a reply within 24 hours. I have never received a definitive response to my complaints, and still no kits. I have asked for refund - but got no response.
RAINBOW LABS ARE A DISGRACE.
